Description
BACKGROUND OF THE INVENTION
Barbecue grill manufacturers commonly supply a wheeled cart with the
barbecue grill for mounting the grill and for moving the grill from one
location to another. The carts are packed in an unassembled state with the
grill for convenience in shipping the product. Such carts, in general,
have the grill mounted centrally thereon with the cooking surface located
at approximately the waist-level of an adult. The cart may include front,
side and/or bottom shelves and wheels or casters on two or four of the
legs.
As a result of the elevated mounting of the grill, barbecue grill carts
tend to be top heavy. Consequently, the carts must utilize multiple braces
or similar means to ensure the stability of the cart. In general, braces
are normally provided between the legs of the assembly, extending from
front to back and from one side to the other, at both upper and lower
regions of the legs. This multiplicity of braces, along with the
corresponding fastening means, causes assembly of the cart to be
relatively complex and time consuming. In addition, problems are
encountered with supply and quality control due to the number of parts
which must be supplied for cart assemblies.
A major improvement in cart design is taught by co-pending application Ser.
No. 392,790, now, U.S. Pat. No. 4,955,358. The number of braces was
reduced substantially while increasing the rigidity of the assembly by
providing interlocking of the braces and multiple contact points at each
leg. It is to further improvement in cart design as well as to the solving
of problems of the prior art with regard to the multiplicity of parts and
relative difficulty of assembly that the present invention is directed.
SUMMARY OF THE INVENTION
It is, therefore, one of the principal objects of the present invention to
provide a cart assembly for barbecue grills that has a very limited number
of structural parts, while exhibiting superior stability.
Another object of the present invention is to provide a cart assembly for
barbecue grills that is easily and quickly assembled by a consumer.
A further object of the present invention is to provide a cart assembly for
barbecue grills that provides economies in manufacturing and in packaging
and which is durable for providing a long service life.
These and other objects are attained by the present invention which relates
to a cart assembly for barbecue grills that is generally rectangular in
shape and normally includes wheels for mobility and an LP gas tank as a
fuel source. The cart assembly includes right and left sets of leg means
with a front and rear leg set being permanently fastened together to form
a leg assembly, thus forming the sides of the cart assembly. In
conjunction with the means used to fasten the front and rear leg members
together, integral mounting means are provided for receiving and securing
the bottom grill casting or firebox thereto. Strut means are provided to
connect the right and left sets of leg means at their lower ends. The cart
assembly also includes a control panel to connect the right and left
assemblies at their upper end and the grill casting itself serves as a
structural element. Side, front, and bottom shelves may also be provided.
Various additional objects and advantages of the present invention will
become apparent from the following detailed description, with reference to
the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an exploded perspective view of the present cart assembly,
illustrating the integral casting mounting means.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now more specifically to the drawings, and to FIG. 1 in
particular, numeral 10 designates generally the present barbecue grill
cart assembly. The cart is shown in exploded form with a barbecue grill
shown to illustrate the mounting arrangement. The structural members of
the cart will normally be fabricated from steel to provide the necessary
strength and resistance to heat; however, other suitable materials having
these qualities may also be utilized.
The present cart includes a right side leg assembly 12 and a left side leg
assembly 14. Each leg assembly includes a front and rear leg and a
connecting strut means extending therebetween. Thus, the right leg
assembly 12 includes a front leg 16, a rear leg 18, and a connecting strut
20. The left side leg assembly includes a front leg 17, a rear leg 19 and
a connecting strut 21. The connecting struts 20 and 21 are disposed
perpendicular to and near the upper ends of the legs 16 and 18, and 17 and
19, respectively, and are fastened therebetween, preferably by welding.
The struts between the front and rear legs may be secured thereto in other
suitable ways; however, welding is preferred for its strength, structural
integrity, and the fact that the combined front and rear leg sets are
assembled during manufacture and prior to shipment. This provides
economies in packaging the cart assembly as the packer need only make sure
that there are two leg assemblies in the carton rather than four legs,
eight braces, etc. In addition, since the barbecue grill and cart assembly
are shipped in an unassembled condition, assembly by the consumer is
greatly simplified.
In the embodiment shown in FIG. 1, the right and left side leg assemblies
are secured to one another by a bottom shelf means 22, disposed
perpendicularly thereto and near the lower ends of the leg assemblies in
one plane, and by a control panel 24 and the grill 26, disposed near the
upper end of the leg assemblies in a parallel plane. The bottom shelf is
formed with strut members 28 which extend horizontally between the cart
legs, being secured thereto in a suitable manner, as with butterfly nuts.
Disposed perpendicularly to the struts 28 are shelf members 29 which
extend across the parallel struts 28 and are secured thereto in a suitable
manner. At the left side of the cart, as viewed in FIG. 1, the large
wheels 32 are secured to the leg members 17 and 19, respectively. At the
right side of the cart, as viewed in FIG. 1, the legs receive casters 34,
which are inserted into the legs from the bottom. This construction is
described in co-pending application Ser. No. 554,661, having a common
assignee. The relevant material from the co-pending application is
incorporated herein by reference.
At the upper end of the leg assemblies, connection across the front is
provided by control panel 24. The panel includes a laterally extending
flange 36 on each side thereof. These flanges and the main body portion 38
of the control panel 24 define a recess therebetween for receiving the
front legs. The main body portion 38, which depends from the sloping
control panel 40, provides a contact point for the leg members on either
side thereof. In addition an abutment means 42 is provided in body portion
38, the abutment means resting on struts 20 and 21 when assembled. Thus,
multiple contact points, the contact points including the flanges 36, the
body portions 38, the abutments 42, and the struts 20 and 21, are provided
to prevent racking or twisting of the cart assembly. The control panel
flanges are then secured to the legs with a suitable fastening means such
as a bolt 41 and nut 43, through corresponding apertures 44 in the flanges
and 46 in the leg members.
Further securement at the upper ends of the leg assemblies is provided by
the barbecue grill casting 26 which rests on and is bolted to the struts
20 and 21, utilizing two integral studs 48 for each side. The studs are
permanently secured to the struts 20 and 21 and extend upwardly from the
struts 20 and 21 and into the casting 26 through apertures formed therein,
where they are secured by nuts 50. This construction facilitates rapid
assembly of the grill and cart, the grill being easily located on the
studs 48, and the permanent fastening of the studs to the side struts
provides additional stability to the overall assembly. The side shelves 52
and 54 are then secured to each side of the cart assembly, at the upper
ends of the leg members.
The grill 26 may be fueled with an LP gas tank (not shown), which is
mounted on the bottom shelf assembly 22 in any suitable manner, such as
with securing clips or other receiving means. The grill may also be fueled
with natural gas or charcoal. The cart assembly may also include a front
shelf, a front wire basket, or a front panel disposed between the front
legs for concealing the gas tank.
It can thus be appreciated by those skilled in the art that a novel
barbecue grill cart assembly and modifications thereof have been shown and
described in detail herein. Various additional changes and modifications
may be made without departing from the scope of the present invention.
